Yen Sinks Near Four-Year Low

The yen plunged to its lowest level in nearly four years and showed no signs of slowing its weakening trend in response to the Bank of Japan's latest push to ease monetary policy.

Investors have been aggressively selling the Japanese currency since policy makers at the BOJ announced last week they will print trillions of yen to pump money into Japan's sluggish economy in a bid to keep interest rates low and spark faster growth.
